In the following detailed description, reference is made to theaccompanying drawings that form a part hereof, and in which is shown byway of illustration specific embodiments in which the inventive subjectmatter may be practiced. These embodiments are described in sufficientdetail to enable those skilled in the art to practice them, and it is tobe understood that other embodiments may be utilized and thatstructural, logical, and electrical changes may be made withoutdeparting from the scope of the inventive subject matter. Suchembodiments of the inventive subject matter may be referred to,individually and/or collectively, herein by the term “invention” merelyfor convenience and without intending to voluntarily limit the scope ofthis application to any single invention or inventive concept if morethan one is in fact disclosed.

The functions or algorithms described herein are implemented inhardware, software or a combination of software and hardware. Thesoftware comprises computer executable instructions stored oncomputer-readable media such as memory or other type of storage devices.Further, described functions may correspond to modules, which may besoftware, hardware, firmware, or any combination thereof. Multiplefunctions are performed in one or more modules as desired, and theembodiments described are merely examples. The software is executed on adigital signal processor, application-specific integrated circuit(ASIC), microprocessor, or other type of processor operating on asystem, such as a personal computer (PC), server, router, or otherdevice capable of processing data, including network interconnectiondevices.

Some embodiments implement the functions in two or more specificinterconnected hardware modules or devices with related control and datasignals communicated between and through the modules, or as portions ofan ASIC. Thus, the exemplary process flow is applicable to software,firmware, and hardware implementations.

Collections of content files may be bundled into a package file andpresented in various ways. For example, considering page descriptorlanguage documents, simple lists or as links for each content file of apackage files may be presented within page description languagedocuments, such as PDF documents. Although such presentation methodsprovide access to the packaged files, various embodiments described andillustrated herein provide more interactive ways to author and presentpackage files. Some embodiments provide mechanisms by which richdescriptions of content files within a package may be presented,allowing a viewer to identify if particular content files are relevantfor a particular need without even opening the particular content files.Some embodiments may allow a viewer to select a mode of presentation ofa packaged file. Some embodiments allow content authors to includegraphics, audio, moving images and videos, and views of package fileswithin a presentation specification to provide graphical representationsof content files included in package files. As an ancillary benefit,presentation specifications may be utilized to include brandinginformation, such as company logos, information, product illustrations,and the like in an interactive presentation. In some furtherembodiments, a content file, or other element of a package file mayoptionally be linked to at another storage location, such as on anetworked server.

In some embodiments, a view of a collection or group (e.g., package) ofcontent files may be presented in a user interface using a customizablenavigation template, which is referred to herein as a presentationspecification. A presentation specification may be an object adapted topresent one or more views of a package file. The views presented by apresentation specification may be user interactive and may include anyof still images, animations, video, audio, and other forms of media. Insome embodiments, a presentation specification may include uniquepackage branding (e.g., a package of files delivered by a company may bebranded using that company's branding). Some such embodiments aresupported by the creation and visualization of metadata regarding thecontent files included in a package file. For example, the content filemetadata may be automatically determined, such as file type, creationdate, length etc., or it may also be user inputted, such as commentaryand notes regarding the package as a whole or the individual contentfiles included therein. In some embodiments, the metadata isindependently embedded within the package file. In other embodiments,the metadata is embedded within content files packaged within thepackage file. The metadata, in some embodiments, may include location(e.g., geospatial) data associated with each content file and abackground or reference image or animation upon which content files areto be displayed as a function of the location data.

Multiple presentation specifications may also be defined for a commonpackage file. In addition, presentation specifications may be madeavailable for package file views. For example, a particular company maypublish a number of presentation specifications for various packagefiles that are typically assembled by that organization, each of thesepresentation specifications including a custom navigation template andorganization-specific branding.

In one example embodiment, a user interface of a presentationspecification may be presented as columns, each column being dedicatedto a particular content file in the package file, including metadataregarding a respective content file of the package file. In anotherembodiment, relationships between content files and the package file maybe indicated. For example, a map may be created which indicates certainrelationships that exist between content files in a package file.

Package files may be authored in several ways. Some embodiments provideuser interfaces that may be manipulated to select one or morepresentation specifications to include in a package file, to set variousoptions, to define metadata, and to attach or otherwise associatecontent files with a package, such as via linking to content filesaccessible over a network. Some other embodiments provide mechanismsthat may be used in a drag-and-drop fashion where a user may selectcontent files to be packaged, such as in a file explorer-type userinterface of an operating system, and drag-and-drop the content filesinto a package file user interface item, such as an icon. The user maythen select one or more presentation specifications for use indisplaying a representation of the content files. These and otherembodiments are described in detail below.

FIG. 1 is a user interface 100 illustration, according to an exampleembodiment. The user interface 100 illustrates a view of a package filepresented according to a presentation specification. The view of thepackage file includes a presentation of three content files created fora recipient. The presentation specification, when instantiated in theuser interface 100, includes a header 102, a body including threecolumns 104, 106, 108, and a footer including an image 122. The packagefile, in some embodiments, is a page description language document, suchas a PDF document.

The header 102, in this embodiment, includes a graphic of an entity(e.g., company, organization, or person) of origin of the package file.The graphic is instantiated from an image file that may also be packagedwithin the package file. However, in some embodiments, the image filemay be referenced by an Internet address in metadata of the presentationspecification. Thus, in the event the entity of origin modifies itsimage file, an updated image file may be stored to the Internet addressand subsequent views of the package file using the presentationspecification will display the modified image file.

The columns 104, 106, 108 of the body portion of the user interface 100include a column for each of three content files, such as documents,included in the package file. The columns, in the example embodiment,each include a title 110, 114, 118 and a description 112, 116, 120. Thetitles and descriptions provide information to a viewer about a contentfile that may be viewed by selecting a respective column 104, 106, 108.For example, a user may desire to view information regarding the user'sauto insurance policy. The user in such an example would select the leftmost column 104, such as by clicking a mouse on the column. Such aselection, in some embodiments, may cause the underlying content file tobe displayed, such as in the user interface 200 of FIG. 2.

FIG. 2 is a user interface 200 illustration, according to an exampleembodiment. The user interface 200 presents the auto insurance policyinformation content file that is referenced by metadata underlying theleft most column 104 of the user interface 100 in FIG. 1. The userinterface 200 includes a header 202 and a body 204. The header 202 inthis embodiment includes the same image file of the header 102 in theuser interface 100 of FIG. 1. However, this image file need not be thesame. This user interface 200 may be defined in a manner completelyindependent of other user interfaces which may be configured to displayother content files included a package file. However, each of thecontent files underlying the columns 104, 106, 108 of the user interface100 of FIG. 1 may be configured for display in the user interface 200.The body 204 is an area within which a selected content file may bedisplayed. The pane in various embodiments may be utilized to presentvarious content file types such as documents, video, images, text, andother file and media types.

The user interfaces 100 and 200 of FIG. 1 and FIG. 2 are merely examplesof presentation specifications (e.g., in the form of a page descriptionlanguage document and/or executable code or scripts) that may becreated, linked, and packaged together by developers and users. Furtherexamples of presentation specifications are illustrated and describedwith regard to FIG. 3 and further with regard to FIG. 9 and severalfigures that follow. Note though that the only real limits on what suchuser interfaces may look like and how they may behave and be linked arerelative to the scope of the presentation specification developer'simagination.

For example, FIG. 3 is an illustration of a hierarchical display elementpresentation specification 300, according to an example embodiment. Sucha hierarchical display element presentation specification 300 mayinclude multiple display elements which may be expanded and contractedby a viewer in a hierarchical fashion when instantiated within a readerand/or player application. Such a hierarchical display elementpresentation specification 300 is therefore viewer interactive.

The example hierarchical display element presentation specification 300includes a top-level display element 302 and multiple lower leveldisplay elements 304. In some embodiments, although the display elementsmay be at different levels in the hierarchy, each display element mayinclude identical data elements. For example, the data elements of eachdisplay element, such as in the illustrated data structure 306 and datastructures of other presentation specifications, may include:

-   -   a display element name;    -   a reference to a parent display element;    -   a reference to a content file within a package file;    -   referenced content file properties, such as file name, size,        type, created date, and modified date;    -   one or more icons or other images that may be used to represent        the referenced content file within the presentation        specification when instantiated;    -   a description of the referenced content file; and    -   a location in which to display the reference content file within        the presentation specification.        In other embodiments, there may be fewer or greater numbers of        data elements and the data elements may be different depending        on what is specified by a presentation specification developer.        Some or all of these data elements may be displayed within a        respective display element, column, presentation specification        hot spot, or other location specified within a presentation        specification. In further embodiments, the display element 304        may be representative of a folder including further content        files and/or folders therein. The display element 304, in such        embodiments, may be associated with a second presentation        specification. Thus, when the display element 304 is selected,        the view presented will be achieved through instantiating a view        of the second presentation specification.

FIG. 4 is a pseudo code listing 400 of a page description languagedocument, according to an example embodiment. The page descriptionlanguage document, in this embodiment, is a package file and includesfive content files packaged therein. The five packaged content filesinclude a presentation specification in 2.0 OBJ, packaged content files1, 2, and 3, and an image file in 6.0 OBJ that is referenced in thepresentation specification, 2.0 OBJ. The pseudo code listing 400includes a call to a presentation specification, 2.0 OBJ. In someembodiments, when a page description language document includes apresentation specification, the presentation specification isinstantiated upon opening the page description language document.

A data structure of a presentation specification that may be included ina package file may include metadata associating each of one or morecontent files within a page description language document to apresentation display element of the presentation specification. However,in some embodiments, the metadata may define display elements to beinstantiated by the presentation specification. A presentation displayelement may or may not be a hierarchical presentation display element.The data structure of the presentation specification may further includedata defining a package file presentation header to be presented with acontent file when selected within a page description language readerapplication for display, such as is illustrated in FIG. 2. In someembodiments, the presentation specification also includes instructionsexecutable within an environment of the page description language readerapplication, or other application depending on the file type of thepackage file, to cause the presentation specification to be instantiatedand displayed within a graphical user interface of the application. Insome embodiments, the instructions may also be executable to modify anappearance of the displayed presentation specification in response toone or more events, such as a user clicking a mouse on a displayelement, a hover event of a mouse over a displayed element, or otherevent.

FIG. 5 is block diagram of logical portions of a system, according to anexample embodiment. FIG. 5 includes one or more presentationspecifications 522 and optional elements 524 that may be selected andmanipulated utilizing an application 500 to author a package file 526.The application 500, in some embodiments, is a page description languagedocument authoring application that includes further modules thatfacilitate authoring of the package file 526. Such modules may include apackage editing module 502, a first player application or plug-ininstance 504, a package host module 514, and a second player applicationor plug-in instance 512. The first and second player applications orplug-in instances 504, 512 may be identical instances of an applicationsor plug-in, such as the FLASH® Player plug-in available from ADOBESYSTEMS INCORPORATED of San Jose, Calif. However, in other embodiments,one or both of the first and second player application or plug-ininstances 504, 512 may include one or more other media presentationapplications or plug-ins capable of presenting media, such as images,animations, still and moving images, audio, and/or other media formats.Examples of such applications and plug-ins may include SilverLightavailable from Microsoft Corporation and QuickTime available from Apple,Inc.

The package editing module 502 and the package host module 514 areapplications encoded according to a format of the respective playerapplications or plug-ins 504, 512 upon which they operate. In someembodiments, the package editing module 502 is operable within theplayer application/plug-in 504 to provide user interfaces that allow apackage file 526 author to select one or more presentationspecifications 522 and one or more optional elements 524 and to specifyproperties and enter other data into the package file 526. The packagehost module 514 is operable within the player application/plug-in 512 todisplay the package file 526 in a player mode and in an authoring mode.While in the player mode, the packages host module 514 is operable toallow a user to interact with a displayed package file 526 according toa presentation specification 522. While in the authoring mode, thepackages host module 514 is operable to reflect changes made to thepackage file 526 by the package editing module 502.

Changes made to the package file 526 via the package editing module 502are communicated to the package host module 514 via a bridge layer 506.The bridge layer 506 may be an interface in the form of a ApplicationProgramming Interface (API) that provides mechanisms by which datarepresentative of data within the package file 526 and changes made tothe package file 526 may be moved and may flow between the package hostmodule 514 and the package editing module 502. For example, when thepackage editing module 502 is used to select one or more of thepresentation specifications 522 for inclusion in the package file 526,data representative of a selected presentation specification is includedin a bridge layer 506 function or method call which causes a referenceto the selected presentation specification to flow to the package hostmodule 514. However, in other embodiments, a data structure of theselected presentation specification may be passed via the bridge layer506.

In some embodiments, due to the programmatic nature of the packageediting module 502, package host module 514, presentation specifications522, optional elements 524, and package file 526, the bridge layer 506is insulated from a host layer 510 of the application 500. The hostlayer 510 may include a kernel or at least some portions of application500. In some embodiments, the insulation of the bridge layer 506 fromthe host layer 510 is provided by a security layer 508. The securitylayer 508 may limit access to some resources of the application, such asaccess to files and other resources of and on a computing device uponwhich the application is present.

FIG. 6 is block diagram of logical portions of a system, according to anexample embodiment. The block diagram of FIG. 6 provides a detailedperspective of a package editing module 600. The package editing module600 is one example embodiment of the package editing module 502 of FIG.5. The package editing module 600 is but one example and may include agreater or lesser number of elements and other modules in otherembodiments.

The package editing module 600, in some embodiments, includes apresentation specification select module 602, an option modificationmodule 604, and a publication module 612. The presentation specificationselect module 602 is operative to provide a user interface to allowselection of a presentation specification 522 held in a storage device620 to which the package editing module 600 has access. The presentationspecification select module 602, upon receipt of a presentationspecification selection, causes data representative of the selection tobe communicated to a package host module, such as the package hostmodule 514 of FIG. 5.

The option modification module 604, in some embodiments, is operative topresent package file authoring options via one or more user interfacesaccording to one or more further modules. The further modules mayinclude one or more of an options module 606, a colors module 608, afile detail module 610, and other modules depending on a selectedpresentation specification, the particular embodiment, permissions of aperson using the package editing module 600, and other factors. In someembodiments, the options module 606 is operable to provide package fileand presentation specification options to a user. Some such options mayinclude security and encryption options, data compression options,options that modify how a presentation specification is displayed withina package host module, and other options that may apply to a packagefile as a whole or in part when displayed. Some further options mayinclude one or more optional elements 524 from the storage device 620which may be selected for inclusion in a package file or which mayalready be included or referenced in a selected presentationspecification 522. Such optional elements 524 may include one or morenavigation aids that provide navigation functionality within a displayedpresentation specification. In some embodiments, the optional elementsmay include another instance of a media playing application or plug-inwhich may be configured to play an audio track, display a video,animation, a series of still images, or other media types whendisplayed. As with the presentation specifications 522, thefunctionality of the optional elements 524 is generally limited only bythe imagination of an optional element developer or package file author.

The colors module 608, in some embodiments, provides one or more userinterfaces operable to receive input to define colors used whendisplaying views of a package file within a presentation specification.The one or more user interfaces, in some embodiments, provide a colorpalette to select colors from or enter color specifications into, suchas red-green-blue (RGB) values. In some embodiments, the colors module608 is operative to receive a selection of one or more presentationspecification elements via a menu item or by user input into the packagehost module 514, of FIG. 5, via the bridge layer 506, also of FIG. 5.The colors module 608 is the operative to receive color specificationinput for the selected elements and to populate the color specificationinput across the bridge layer 506 to cause the color specification inputto be reflected in a view of the package file within the package hostmodule 514.

In some embodiments, the file detail module 610 is operative to provideone or more user interfaces to allow users to define and manipulatemetadata associated with a selected presentation specification andcontent files within a package file. Such user interfaces may allow auser to add, delete, and modify metadata fields and associate thosemetadata fields with content files within the package file or to thepackage file itself. The metadata fields may be designated for displayor made invisible. In some embodiments, the metadata fields may bedefined to hold descriptions of content files; to hold location (e.g.,geospatial) data, such as latitude and longitude, of a location to whicheach content file is relevant; hold an X, Y coordinate pair mapping toan image location to which each content file is applicable; hold a dateto which each content file pertains; and many other metadata types. Insome embodiments, the metadata may provide additional functionalitypossibilities, such as automatic mapping of content files to locationswithin a reference image or animation, such as a map or calendar, as afunction of the metadata.

In some embodiments, the file detail module 610 or other module may alsoinclude one or more user interfaces which may be used to view thecontents of the storage device 620 or other local and/or remote storagedevices. Such user interfaces may be used to view drive/folder/file typeviews of the storage devices and allow selection of one or more files tobe included in the package file.

The publication module 612, in some embodiments, is operative to receiveinput specifying how to perform one or more functions with an authoredpackage file. The one or more functions may include saving and/ordistributing the package file. These functions may be accomplishedthrough one or more, or a combination of, a save module 614, an emailmodule 616, and a document center module 618.

The save module 614 is operative to present a user interface to save apackage file to a storage device, such as the storage device 620. Insome embodiments, the save module 614 leverages one or more functions ofa host application, such as application 500 of FIG. 5, to store thepackage file. Such functions may include displaying a user interfaceproviding a drive/folder/type view to receive input specifying where thepackage file is to be stored.

The email module 616, in some embodiments, is operative to call an emailclient present on a computing device upon which the package editingmodule 600 is operating to attach the package file to an email, whichmay then be addressed and sent using the email client. In someembodiments, an email client may be present within the email module ormay be included within the application 500 of FIG. 5. In suchembodiments, one or a series of user interfaces may be provided toreceive one or more email address of intended recipients, a message, andthe package file. The received input may then be sent via emailutilizing a default email server or an email server identified in aconfiguration setting.

The document center module 618, in some embodiments, is operative topublish package files to a location where one or more users may accessthe document. The location may be a collaboration server. In some suchembodiments, the document center module 618 is operative to instantiatea collaboration session on a collaboration server and embeds anidentifier of the instantiated collaboration session within the packagefile. The package file may then be stored on the collaboration server.In some such embodiments, one or more user interfaces may also beprovided to a user to select or enter one or more other users to thenreceive a notification of the instantiated collaboration session. Insome other embodiments, after the collaboration session identifier isembedded within the package file, the package file may then bedistributed via the email module 616 and/or stored using the save module614. In these embodiments, when other users open the package file, theapplication within which the package file is viewed, such as a pagedescription language reading application, may connect to thecollaboration server and download comments and other data and display arepresentation of some or all of the downloaded data within the packagefile. The page description language reading application may also allow aviewer of the package file to enter comments or perform other actions,such as approving, and store data representative of the actions or ofthe comments to the collaboration server for other users or processes tosee and use.

FIG. 7 includes block diagrams of various page description languagedocuments 710, 720, 730, according to example embodiments. While theexample embodiment is described in the context of page descriptionlanguage documents, it will be appreciated that other embodiments may beimplemented using types of documents and content. Each of theillustrated page description language documents 710, 720, 730 isslightly different from the others. The form of page descriptionlanguage documents, when taking the form of a package file, may varyfrom embodiment to embodiment based on the nature of the one or morepresentation specifications utilized in presenting the package file.Further, in some embodiments, such as in the page description languagedocument 720, the presentation specification is not even included in thepage description language document 720, but instead is referenced in thepackage file presentation metadata:

A first page description language document 710 includes contentattachments, such as one or more content file attachments and metadatafor each of the one or more file attachments. The page descriptionlanguage document 710 further includes a presentation specification andnavigator data for use by the presentation specification in presentingone or more views of the page description language document 710. Thepage description language document 710 further includes a header contentitem and header data defining how the header content item is to bedisplayed. The page description language document 710 also includes awelcome content item and welcome data defining how the welcome contentitem is to be displayed. A welcome content item is generally a firstview of the page description language document 710 displayed when thepage description language document 710 is first opened. A displayedwelcome content item may be thought of as a “splash screen” in someembodiments.

A second page description language document 720 takes a different formfrom that of the first page description language document 710. Thesecond page description language document 720 includes one or more fileattachments and each file attachment includes embedded metadata. Thepage description language document 720 further includes package filepresentation metadata, which includes a reference to at least apresentation specification and metadata of how the presentationspecification is to be instantiated and presented. When the pagedescription language document 720 is opened, a suitable application forpresenting a view of the page description language document 720 mayidentify that there is a reference to a presentation specification andobtain a copy thereof from a referenced location, such as an Internet orother network location, by download. The application for presenting theview of the page description language document 720 may then extract themetadata embedded in each of the file attachments. The presentationspecification is then instantiated as a function of the package filepresentation metadata and the extracted file attachment metadata.

A third page description language document 730 takes yet another form.The page description language document 730 includes one or more fileattachments and metadata for each file attachment. The page descriptionlanguage document 730 also includes a presentation specification and aheader content item. The presentation specification will be instantiatedas a function of the file attachment metadata. The header content item,in such embodiments, includes enough information so as not to requirefurther data to instruct it how to instantiate.

Each of the page description language documents 710, 720, 730 includes adifferent form as described and illustrated. This is not intended to bea listing of all forms that page description language documents that arepackage files may take. Instead, the embodiments in FIG. 7 are examplesas to the flexible nature of package files.

FIG. 8 is a logical block diagram of a presentation specification 800,according to an example embodiment. The presentation specification 800may include various elements, including an item viewer that is operativeto instantiate one or more instances of an item renderer. An itemrenderer, when instantiated, is operable to render a view of an item,such as a content file or folder included in a package file. Such itemrenderer views are typically generated as a function of metadataincluded in or otherwise referenced by a package file to be display. Anitem renderer may include one or more display states that may changeupon occurrence of an event, such as a mouse hover or receive focusevent. An item renderer may also include one or more animation functionsthat animate a view of an item between states display. The item vieweris also operable to receive input to modify which item renderers aredisplayed or to modify which content files are represented by theinstantiated item renderers. The item viewer, in some embodiments,includes one or more animation functions to animate transitions betweenthe displayed item renderers or the content files represented by theinstantiated item renderers.

The presentation specification 800, and elements therein, may be definedor configured in metadata. In some such embodiments, the presentationspecification 800 may include executable code that implementsfunctionality of the particular presentation specification. In someembodiments, the code is in a runtime scripting language, such as JavaScript, Visual Basic (VB) Script, Action Script, and the like. Such codeallows authors to add scripting and code to presentation specificationsto implement functionality of various elements. Such code may beexecutable within an application or application plug-in, such as theFLASH® Player application plug-in, discussed above, or otherapplications or application plug-ins. In other embodiments, the code iscompiled code writing in a language, such as C/C++, capable ofimplementing the desired functionality, which may be accessed andexecuted within or caused to be executed by an application within whicha package file is to be viewed.

In some embodiments, the item view animation functions include at leasttwo animation functions. A first animation function is called when userinput is received to navigate through item renderer views in a slowfashion, such as between two adjacent item renderers. A second animationfunction may be called when user input is received to navigate throughitem renderers in a fast manner, such as from a first item renderer to alast item renderer, or such as when there are large number of itemrenderers or content files represented by the item renderers.

The presentation specification 800 may also include a “crumbs list”element that display is a crumbs list within an interface. A crumbs listis a representation of a relative location within a package file. Forexample, a package file may include a first level of content itemorganization including a file and two file folders. One of the filefolders may include a few more files. When viewing the package filecontent files, initially the crumbs list may include text “HOME.” A usermay then select one of the two file folders to cause the files of theselected file folder to display, thereby causing the crumbs list todisplay “HOME/FOLDER A” where “FOLDER A” is the selected folder.

The presentation specification 800 may also include a file count elementthat displays a count of a number of files included in a selected viewwithin the item viewer. This count may be a simple count of the numberof files. However, in some embodiments, the count may identify whichfiles of a count of files are currently displayed within the itemviewer. For example, the file count element may provide, “FILES 4-7 of14.”

In some embodiments, the presentation specification 800 may include afolder label element. A folder label element provides the name of thefolder currently being viewed within the item viewer. As with the crumbslist described above, in an initial view, the folder label element mayprovide “HOME.” When folder A is selected for view, the folder labelelement will then provide “FOLDER A.”

The presentation specification 800 may also include one or morenavigation aids. A navigation aid is an element that provides mechanismsthat represent files within a package file that may be selected tonavigate to the represented files. Some such representations may includeone or more of folders, groups of files, file types, and other logicalunits that may be provided based on the specific navigation aid includedin the presentation specification 800 and the requirements of thespecific embodiment. For example, one navigation aid may provide iconsrepresentative of image files, audio files, word processing documentfiles, and “other files.” Selection of the image files icon will causethe item viewer to change the view it presents, including theinstantiated item renderers, to a view that includes only image filesincluded within the viewed package file. Another navigation aid mayprovide a folder view, including icons and labels of folders, includedwithin a displayed package file that may be selected to navigate to therespective folders. Yet another navigation aid may present arepresentation of all files included within a displayed package file, ordisplayed folder therein. The package file may include fifteen files andthe navigation aid may include an icon for each of the fifteen files.Selection of one or more of the icons in such an embodiment will causethe item viewer to navigate to a view including the file represented bythe selected icon. In some such embodiments, the icons representative ofthe files that are currently displayed are modified to indicate that thefiles represented by the modified icons are currently displayed withinthe item viewer. Such modification may include an outlining of the icon,display of an alternate icon, backlighting an icon, animating an icon,or other modification that will graphically convey the fact that thefile represented by an icon is currently displayed within the itemviewer.

Some embodiments may also include one or more navigation user interfacecomponents, such as a tree-view type component. In such embodiments, thenavigation user interface component may provide a tree-view of afolder/file structure of a package file. In some embodiments, the filesand folder of a package file may be an export from an email client andinclude emails arranged in folders, such as inbox, sent items, deleteditems, and the like. In such embodiments, the tree-view provides afolder representation of each folder that may be expanded and collapsedto view and hide subfolders. Selection of a tree-view item in suchembodiments causes the item viewer to display the contents of the folderrepresented by the selected item.

In yet further embodiments, the presentation specification 800 may alsoinclude toolbar extras. Toolbar extras may cause a toolbar button to bedisplayed within a user interface of an application displaying arepresentation of a package file as a function of the presentationspecification 800. A toolbar extra, in one embodiment, may be a toolbarbutton that triggers a process encoded within the presentationspecification 800 to import email from an email client or allows a userto select files for inclusion in the package file. A toolbar extra inother embodiments may include a “SEARCH” button that provides mechanismby which a package file, and/or content files therein, may be searched.In some such embodiments, various search options may be provided such asa global package file text search, package file type specific searches,searches based on types of data included in a package file or contentfiles therein, such as CAD related data, geospatial metadata, dates, andother data types. Other toolbar extras may trigger one or more otherprocesses and may utilize code embedded within the presentationspecification 800 and or the application displaying the representationof a package file.

The presentation specification 800 also includes authoring controlswhich may be used when authoring a package file with regard to apresentation specification. The presentation specification 800 includestwo modes of display. The first mode is an authoring mode which isoptionally viewable within an application providing package fileauthoring functionality and allows modification of the package file andconfiguration of the presentation specification 800. The second mode isa viewing mode and only allows a user to view and navigate throughcontent within a package file.

The authoring controls may include item viewer specific extras, generalauthoring controls, and other controls based on the specificpresentation specification selected. The authoring controls may providefunctional user interface elements that allow a user to add files, orreferences thereto, to a package file. The authoring specific extras mayallow a user to configure item viewer or item renderer controls, such asselecting optional animation functions, display sizes, metadata todisplay within an item renderer, and other display options. The generalauthoring controls may include options such as which navigation aids touse or display, the setting of icons used in displaying various elementsof the navigation aids, the navigation user interface component, andinclusion and/or configuration of the crumbs list, folder label, filecount, and toolbar extras. Other authoring controls may be providedbased on the elements included within a particular presentationspecification 800 that may be selected.

FIG. 9 is a user interface 900 illustration generated as a function of apresentation specification, according to an example embodiment. The userinterface 900 includes a header 902, a crumbs list element 904, a filecount element 906, and a folder label element 908. The user interface900 further includes a card listing 910 of content files packaged in apackage file the user interface 900 represents.

The header 902 is configured in metadata and may include various textualelements, graphics, audio tracks, animations, and other media types. Inthe present embodiment the header 902 includes only text.

The crumbs list element 904, file count element 906, and folder labelelement 908 illustrate examples of these elements as described withregard to FIG. 8. Note, though, that the card listing 910 is a listingof cards identified by the “FOLDER NAME” in both the crumbs list element904 and folder label element 908. Further, the file count element 906 isa count (27) of the files in the “FOLDER NAME” folder and identifieswhich files (21-27) are displayed.

The cards displayed in the card listing 910 each include a thumbnailimage (shown as a black box) and a description of the file eachrespective card represents. Selection of a card, such as bydouble-clicking with a pointing device, will cause the file representedby the card to be displayed, such as in the user interface 200 of FIG.2. In some embodiments, a card may represent a folder including furtherfiles. In such instances, selection of a card that represents a folderwill cause the crumbs list element 904, the file count element 906, andthe folder label element 908 to be modified to display appropriate databased on the selected folder and the card listing 910 will then displaycard representative of the files therein. However, in some embodiments,a folder may be configured with a difference presentation specificationand the contents of the folder will be displayed in accordance with thatpresentation specification.

The card listing 910 is illustrated in an authoring mode. When in theauthoring mode, the card listing will include a card 912 that allows anauthor to add a file and add an image to the card of the file. To add afile, the author selects the card, such as through use of a pointingdevice or other input device. The author is then presented with one ormore user interfaces that may be used to select a file to be packaged inthe package file or to attach an image to a card. In some embodiments,the card 912 may also allow an author to create a folder. In suchinstances, the author may be allowed to not only create a new folder,but also to associate a presentation specification with the new folder.

The card listing 910, when in the authoring mode, may also allow a userto drag and drop files and folders from outside of the user interface900 into the card listing 910. Folders and files may also be movedaround within the card listing in some embodiments. This may includeselecting one or more cards and dragging and dropping the selected cardsinto a displayed folder. The package files represented by the selectedcards and the cards themselves are then reorganized to be included inthe folder to which the cards were moved. The code to facilitate theauthoring mode of the presentation specification may be included in partin the presentation specification, to accommodate for specific authoringoptions and functionality of the presentation specification, and withinan application within which the package file is being authored, such asa page description language authoring application. Such authoringfunctionality is generally available in each of the presentationspecifications described and illustrated herein.

In a display or non-authoring mode, the “add file” card 912 is notdisplayed and the files and folders within the package file may not bereorganized.

FIG. 10 is a user interface 1000 illustration generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1000 also includes a header 1002, a crumbs list element1004, a file count element 1006, and a folder label element. The header1002 illustrates another example of how a header may be configured. Theheader 1002 includes an image and text. As noted above, the image may beanimated, such as by including a FLASH® enabled SWF type animationwithin the header or an animated GIF image.

The user interface 1000 includes a horizontal card listing 1008 that maybe navigated through by using navigation arrows 1010 and 1012. Each cardof the horizontal card listing 1008 is representative of a file orfolder packaged in a package file. Each card may be configured toinclude various elements that convey what content is included in thefile or folder the card represents. The various elements may includetext, images, animation, audio, and other media types. These elementsmay be customized in some embodiments through definition of metadatatypes and entry of the metadata.

In some embodiments, the cards of the horizontal card listing 1008 areinstances of an item renderer instantiated by an item viewer. The itemrenderer and item viewer are included in the presentation specificationas described and illustrated with regard to FIG. 8. In some instances,the item viewer includes code or a configuration setting specifying anumber of cards to display and then instantiates an item renderer foreach of the number cards to display. In such instances, the item viewerthen instantiates the number of item rendered and populates eachinstantiated item renderer with metadata of the file to be displayed.For example, if the number of cards to display is three, the item viewerwill instantiate three instances of the item renderer in appropriatelocations within the horizontal card listing 1008. The item viewer willthen populate the instantiated item renderers with data to be displayed.That data, when first presenting a view of the package file, may be thedata of the first three files in the package file.

Next, when a user navigates through the horizontal card listing 1008using the arrows 1010 and 1012, the item viewer tracks a displayedposition within the package files and moves the package file through theinstantiated item viewers. Thus, three item viewers will be displayedand recycled by moving data sequentially through the item viewers as auser traverses the package files. In some embodiments, though, a usermay wish to jump from files 1-3 to files 10-12. In such instances, theitem viewer may skip displaying and moving the data of files 4-9 andjump directly to the data of files 10-12.

When navigating through the horizontal card listing 1008, the itemviewer may animate transitions from one set of displayed cards toanother. For example, the animation may cause the cards of thehorizontal card listing 1008 to appear as if they are movinghorizontally. If a user jumps, such as the jump from files 1-3 to files10-12, a second navigation may blur the horizontal card listing 1008 tosimulate the displayed cards moving rapidly. Other animations arepossible and may be presentation specification specific. However, insome embodiments, animations may be reused between presentationspecifications. In such instances, the code and/or media to cause suchanimations may be included as function calls in the application withinwhich the package files may be authored and/or viewed.

In further embodiments, other elements of presentation specificationsmay also be included in the application within which the package filesmay be authored and/or viewed. For example, item viewer and itemrenderer abstractions and extensions may be included in the applicationand called by code or referenced by metadata included within apresentation specification.

FIG. 11 is a user interface 1100 illustration generated as a function ofa presentation specification, according to an example embodiment. Thepresentation specification includes a card presentation 1102. Each cardof the card presentation 1102 represents a file or folder includedwithin at least a portion of the package file, or a metadata referenceto a file or folder located elsewhere that may be viewed within the userinterface 1100 of the presentation specification.

The card presentation 1102 includes cards as described above. However,in some embodiments, the cards may be images derived from an image fileor other file a respective card represents. The cards of the cardpresentation 1102 are randomly scattered across the card presentation1102 portion of the user interface 1100. In some embodiments, the random(or a semi-random) distribution is made according to a set of rules orparameters which may be hard coded within a presentation specificationor provided as display options within the presentation specificationauthoring controls as illustrated and described with regard to FIG. 8.For example, such rules or parameters may specify a size of the cardpresentation 1102 area of the user interface 1100, a size for each card,one or more formulas for calculating a rotation orientation of eachcard, a tilt perspective, an opacity of each card, whether or not thecards may overlap one another when displayed, and other rules orparameters that may affect how the cards are displayed. When a userselects a card within the card presentation 1102, the card may bezoomed-in on, such as is illustrated in FIG. 12.

FIG. 12 is a user interface 1200 illustration generated as a function ofa presentation specification according to an example embodiment. Thepresentation specification of the user interface 1200 may be the samepresentation specification of the user interface 1100 of FIG. 11. Theuser interface 1200 provides the zoomed-in view of the card selectedwithin the card presentation 1102 of FIG. 11. The user interface 1200includes the selected card 1202 and provides a larger zoomed-in view ofit. An animated transition between the card presentation 1102 and thezoomed-in view of the card 1202 may be provided by the presentationspecification to show the card 1202 getting larger and portions of thecard presentation 1102 going out of view. Within the user interface1200, other cards of the card presentation 1102 may still be in view,but be smaller in relation to the larger card 1202. The smaller cardsmay have greater opacity causing them to appear faint within a display.The card 1202 may then be selected to cause a view of the filerepresented by the card to be displayed, such as in the user interface200 of FIG. 2 or within another application suited for displaying thefile, such as an image editing application if the file is an image or aword processing application if the file is a word processingapplication. In some embodiments, selecting the file may cause the fileto be transmitted over a network, such as the Internet, to a networkhosted application to allow viewing and/or editing of the file in thenetwork hosted application. In some such embodiments, if the file ismodified and resaved, the file may be stored back to the package fileover the network.

If a user no longer wishes to view the zoomed card 1202, the user mayuse a pointing device or other input device to signify that intent byselecting an area outside of the card 1202 and the card presentation1102 of the user interface 1100 will return.

FIG. 13 is a user interface 1300 illustration generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1300 includes a crumbs list element 1312 and a file countelement 1314, both as described and illustrated with regard to FIG. 8.The user interface further includes a view of grouped files 1306, 1308,1310. Each group of files 1306, 1308, 1310 also includes a label, suchas label 1316 “MANUALS” for group 1310. The groups 1306, 1308, 1310 areindividually displayed within an item renderer under control of an itemviewer as discussed above. The groups 1306, 1308, 1310 may be traversedusing navigation arrows 1302, 1304.

The groups 1306, 1308, 1310 are each represented by a stack of cards.Each card may be representative of a file within a folder of therespective group. Each card may include an image or animation, adescription, and/or other data. The cards typically over lap each otherexcept a top card which is fully viewable.

FIG. 14 is a user interface 1400 illustration generated as a function ofa presentation specification, according to an example embodiment. Theuser interface is another view presented by the same presentationspecification as in FIG. 13. The user interface 1400 includes a pointer1402 under control of an input device of a computing device, such as themouse of a PC. The pointer is hovering over the “MANUALS” group 1310.The hover event causes the group 1310 to move the cards of the group1310 to allow a larger portion of the stacked cards to be displayed. Insome embodiments, a description bubble 1404 may also appear upon thehover event. In some embodiments, rather than a hover event, a singleclick event with the pointing device may cause the expanded view of thecards and the description bubble 1404 to appear. Selection of a group,such as the “MANUALS” group 1310, causes another user interface to bedisplayed, such as a user interface of another presentationspecification. This user interface may be generated as a function of anyof the other presentation specifications described and illustratedherein. One user interface generated as a function of anotherpresentation specification is illustrated in FIG. 15.

FIG. 15 is a user interface 1500 illustration generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1500 includes a crumbs list element 1502, file countelement 1504, and a folder label element 1506 as described andillustrated above, including with regard to FIG. 8. The user interface1500 also includes a horizontal card listing of card 1512, 1514, and1516 as illustrated and described above with regard to the horizontalcard listing 1008 of FIG. 10. The cards 1512, 1514, and 1516 may betraversed using navigation arrows 1508, 1510. The cards 1512, 1514, 1516of the horizontal card listing in FIG. 15 are cards of the “MANUALS”group 1310 as selected in the user interface 1400 of FIG. 14. In someembodiments, the user interface 1500 of FIG. 15 may also include anotherelement that displays the text displayed within the description bubble1404 of FIG. 14.

In some embodiments, the user interface 1500 may also include anavigation aid 1518. The navigation aid 1518 provides a groups viewsimilar to that of FIG. 13 and FIG. 14. The groups may include hover orselection events as described above with regard to FIG. 14 and may benavigated through using the provided navigation arrows. Selection of agroup in the navigation aid 1518 causes the user interface 1500 tonavigate to the selected group and display the cards in the horizontalcard listing of the group selected in the navigation aid.

Selection of a card in the horizontal card listing, such as card 1512,may cause another user interface to be displayed as a function ofvirtually any other presentation specification illustrated and describedherein. For example, selection of the card 1512 may cause the userinterface of FIG. 16 to be displayed.

FIG. 16 is a user interface illustration 1600 generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1600 includes a crumbs list element 1602, file countelement 1604, and a folder label element 1606 as described andillustrated above, including with regard to FIG. 8. The user interface1600 also includes navigation arrows 1608, 1610 to navigate to adjacentfiles within a package file. In the user interface 1600, a selected card1612, such as the card 1512 of FIG. 15, is displayed. The card 1612 maybe a card as described elsewhere herein and may include one or more oftext, images, animations, and other media types. The user interface 1600also includes a detail area 1614 where details of the file or other itemrepresented by the card are displayed. These details may be included inthe metadata of the package file and associated with the selected card1612. In some embodiments, the user interface 1600 may also include oneor more action elements, such as toolbar extras as described above withregard to FIG. 8 or an action button 1616. Selection of the actionbutton 1616 may cause a data processing activity to be triggered. Forexample, the user interface 1600 includes data representative of an itemavailable for purchase. Selecting the action button, such as through amouse click or other received input, triggers a process which allows auser to purchase the item. This action may include launching a webbrowser to open a specific universal resource locator (URL) or maylaunch an interface to allow a user to enter purchasing information,such as credit card numbers, shipping addresses, and the like.

In some embodiments, the item represented in the user interface 1600 isa content item embedded within the package file being viewed. However,the content item may be secured and not available for viewing, playing,or other mode of consumption unless the item is purchased. In suchembodiments, a user may select the “BUY NOW” action button, provide therequested purchase information through a user interface of the packagefile, such as a user interface generated as a function of anotherpresentation specification or through a web site, and then be allowed toconsume the content item represented within the user interface 1600.

Thus, the series of user interfaces 1300, 1400, 1500, and 1600 of FIG.13, FIG. 14, FIG. 15, and FIG. 16 may be configured within one or agroup of package files to distribute and present an interactive catalogof products. Some such products may also be included in the one or morepackage files. Such products included with the package files may includetextual documents, such as digital books, word processing documenttemplates, and premium textual content. Premium textual content mayinclude proprietary mailing and contact lists, and audio recordings,such as audio books, music, and mobile telephone ringtones. The productsmay also include video, such as movies and television shows, and othercontent, which may be included in a secure manner in an electronic file.In some embodiments, the package files may be viewed and purchases maybe made using a PC, a mobile computing device such as a laptop,smart-phone, or handheld computer, and other computing devices such as aset-top box coupled to a television, display monitor, or otheraudio/visual device.

FIG. 17 is a user interface 1700 illustration generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1700 includes a header 1702 and a reference image 1704.Displayed with reference to the image 1704 are markers 1706 and 1708.The markers are defined in the metadata. The metadata includes a mappingto a location within the image 1704 in which the markers are to beplaced when the image is displayed. In the illustrated example, theimage 1704 is an image of a soccer stadium where tickets are availablein the sections identified by the markers 1706, 1708. In otherembodiments, the image may be virtually any image, such as an image ofan automobile and including markers identifying items selected formarketing, such as a marker of a wheel of an automobile image toidentify high performance tires and braking systems of the automobile.The markers may also include textual descriptions, which are displayedor are displayed upon an event such as a pointer hovering over themarker. In some embodiments, an event such as a hover event or selectionevent of a marker may cause a portion of the image 1704 to becomeanimated, such as a wheel on the automobile rotating, or for audio toplay, such as a sound of a soccer crowd cheering upon a hover event withregard to one of the markers 1706, 1708.

Selection of one of the markers 1706, 1708 may also cause another userinterface to launch, such as one of the other user interfaces describedherein, that is generated as a function of the presentationspecification. In some embodiments, selection of one of the markers1706, 1708 may cause a web browser to be launched to display a webpageproviding further information or allowing a user to make a purchase thatis related to the selected marker, such as purchasing tickets to asoccer game or requesting further information with regard to a displayedautomobile. In some embodiments, selection of a marker 1706, 1708 maytrigger launching of an application, such as a FLASH® based application,that allows a user to make a purchase without departing from theapplication within which the user is viewing the package file.

In further embodiments, selection of a marker 1706, 1708 may causeanother, more detailed image to replace the displayed image 1704. Forexample, if the user selects marker 1706 “UPPER DECK SEATS AVAILABLE,”the stadium image 1704 is replaced with an image of a seating chart ofan upper deck seating section of the stadium. This provides ahierarchical option for linking files within a package file similar tothat illustrated and described with regard to FIG. 3.

The markers may be placed on the image in an authoring mode by selectinga menu item to add a marker or selecting a file from a listing of filesand then placing moving the marker around in a drag-and-drop fashion. Inother embodiments, the image may include metadata defining areas of theimage. Files embedded within a package file may include metadatareferencing one or more locations defined within the image metadata. Insuch embodiments, an item viewer of a presentation specification, orother code element in the presentation specification or application fordisplaying a package file, may place the markers on the image as afunction of the image metadata and the file metadata.

FIG. 18 is a user interface 1800 illustration generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1800 includes a header 1802 as described elsewhereherein. The user interface 1800 also includes an animation 1804. Theanimation 1804, in some embodiments, may be navigated by moving apointer around within the user interface and with regard to theanimation 1804. In the illustrated example, the animation is a globe.Moving the pointer toward the right and left edges causes the animation1804 to cause the globe to appear as if it is rotating on northern andsouthern poles.

User interface 1800 also includes markers 1806 mapped to locationswithin the animation. For example, the illustrated globe animation mayinclude geospatial data defining a latitude and longitude with regard tothe animation. The markers 1806 may be mapped using metadata defining alatitude and longitude where each respective marker is to be located. Inother embodiments, regions may be defined with animation 1804 metadataand marker locations identified with regard to the defined regions. Suchregions may be defined with regard to data represented within theanimation, such as North America.

When authoring a package file using an animation such as is illustratedin FIG. 18, an authoring user interface may be provided that allows anauthor to select an animation, or other image, and define referenceareas within the animation. For example, a simple X, Y coordinatestructure could be assigned. In other embodiments, an interface allowinga user to define regions may be provided. In some embodiments though, ananimation or other image may be provided in a presentation specificationthat already includes addressable metadata, such as latitude andlongitude with regard to a globe or map. In such instances, in anauthoring mode, a user may be presented with a latitude and longitudeentry user interface to enter coordinates as to where a marker is to beplaced.

In further embodiments, markers may automatically be placed within ananimation, or other image, for a content file added to a package file.In such embodiments, the file may include metadata defining a locationwhere a marker representative of the file is to be placed. That metadatamay define a latitude and longitude coordinate set as described above.The metadata may alternatively identify another location as definedwithin the metadata of the animation or other image.

In some embodiments, each marker may also include descriptive text, ananimation, an audio file, or data that may presented upon an eventoccurrence with regard to a respective marker. For example, a marker islocated within the animation 1804 at a location with regard to NorthAmerica and a description bubble 1808 pops up upon a mouse-over event.In another embodiment, an audio file could be triggered upon themouse-over event.

In some embodiments, selection of a marker or other location within theanimation 1804 may cause another user interface to display. In someembodiments, the other user interface may be related to the areaselected within the animation 1804 or other image. For example, if theanimation 1804 were a computer-aided drafting (CAD) image or animation,an area selected may be a part that is further described in a moredetailed CAD file that is identified in the metadata of the one or moreCAD files. In such an instance, the detailed view of the selected CADimage or animation may be displayed in the user interface 1800 or otheruser interface. In another example embodiment, an area of the globeanimation 1804 illustrated in FIG. 18 may be selected. The selected areamay be represented in a zoomed-in map included in the package file beingpresented as identified in metadata of the package file or of one ormore of the package files. In such an instance, the zoomed-in map may bepresented, such as in the user interface of FIG. 19.

FIG. 19 is a user interface illustration 1900 generated as a function ofa presentation specification, according to an example embodiment. Theuser interface 1900 includes the zoomed-in view of the selected area ofthe animation 1804 of FIG. 18 described above. The user interfaceincludes an image 1902, which in this instance is a map, but could be aCAD or other image in other embodiments. The image may be an animationin some embodiments. The user interface 1900 includes further markersmapped to locations within the image as discussed above with regard toFIG. 17 and FIG. 18.
